关于循环格码的存在性

On the Existence of Cyclic Lattice Codes

Chengpin Luo, Brian M. Kurkoski

AI总结:

本文研究嵌套格码成为有限循环群的条件,通过求解线性丢番图方程给出任意码本大小的循环格码设计,使其具备群同构性质,以支持计算转发等物理层网络中继应用。

摘要:

若成形格 $Λ_s$ 包含于编码格 $Λ_c$,即 $Λ_s \subseteq Λ_c$,则二者构成嵌套格码 $\mathcal{C}$。在某些条件下,$\mathcal{C}$ 是通过矩形编码形成的有限循环群。本文给出了此类 $\mathcal{C}$ 存在的条件,并提供了若干设计。这些设计对应于线性丢番图方程的解,使任意码本大小 $M$ 的循环格码 $\mathcal C$ 都能具有群同构;对于将嵌套格码应用于计算转发等物理层网络中继技术而言,这是一项 essential 的性质。

英文摘要:

A coding lattice $Λ_c$ and a shaping lattice $Λ_s$ forms a nested lattice code $\mathcal{C}$ if $Λ_s \subseteq Λ_c$. Under some conditions, $\mathcal{C}$ is a finite cyclic group formed by rectangular encoding. This paper presents the conditions for the existence of such $\mathcal{C}$ and provides some designs. These designs correspond to solutions to linear Diophantine equations so that a cyclic lattice code $\mathcal C$ of arbitrary codebook size $M$ can possess group isomorphism, which is an essential property for a nested lattice code to be applied in physical layer network relaying techniques such as compute and forward.
